Piping and Instrument Diagram
A piping and instrumentation diagram (P&ID) is a schematic illustration of functional relationship of piping, instrumentation and system equipment components, and it contains more details than a PFD. It includes major and minor flows, control loops and instrumentation. P&IDs are used by process technicians and instrument and electrical, mechanical, safety, and engineering personnel.
The instrument symbols used in these drawings are generally based on International Society of Automation (ISA) Standard.
P&IDs play a significant role in the maintenance and modification of the process that it describes. During the design stage, the P&ID also provides the basis for the development of system control schemes, allowing for further safety and operational investigations, such as a Hazard Analysis and Operability Study commonly pronounced as HAZOP. With a few mirrors and a degree in hieroglyphics, anyone can learn to read a P&ID in a short time. Therefore, piping and instrumentation diagram is a topic that can benefit process, project and design engineers, business developers, operators, safety, maintenance and even management.
